Coherent spin-valley oscillations in silicon
Xinxin Cai, Elliot J. Connors, John M. Nichol
Electron spins in silicon quantum dots are excellent qubits because they have long coherence times, high gate fidelities, and are compatible with advanced semiconductor manufacturi…
How valley-orbit states in silicon quantum dots probe quantum well interfaces
J. P. Dodson, H. Ekmel Ercan, J. Corrigan +7
The energies of valley-orbit states in silicon quantum dots are determined by an as yet poorly understood interplay between interface roughness, orbital confinement, and electron i…
Charge-noise spectroscopy of Si/SiGe quantum dots via dynamically-decoupled exchange oscillations
Elliot J. Connors, JJ Nelson, Lisa F. Edge +1
Electron spins in silicon quantum dots are promising qubits due to their long coherence times, scalable fabrication, and potential for all-electrical control. However, charge noise…
Probing the Spatial Variation of the Inter-Valley Tunnel Coupling in a Silicon Triple Quantum Dot
F. Borjans, X. Zhang, X. Mi +5
Electrons confined in silicon quantum dots exhibit orbital, spin, and valley degrees of freedom. The valley degree of freedom originates from the bulk bandstructure of silicon, whi…
Coherent control and spectroscopy of a semiconductor quantum dot Wigner molecule
J. Corrigan, J. P. Dodson, H. Ekmel Ercan +12
Multi-electron semiconductor quantum dots have found wide application in qubits, where they enable readout and enhance polarizability. However, coherent control in such dots has ty…
Direct measurement of electron intervalley relaxation in a Si/SiGe quantum dot
Nicholas E. Penthorn, Joshua S. Schoenfield, Lisa F. Edge +1
The presence of non-degenerate valley states in silicon can drastically affect electron dynamics in silicon-based heterostructures, leading to electron spin relaxation and spin-val…
Low-frequency charge noise in Si/SiGe quantum dots
Elliot J. Connors, JJ Nelson, Haifeng Qiao +2
Electron spins in silicon have long coherence times and are a promising qubit platform. However, electric field noise in semiconductors poses a challenge for most single- and multi…
Circuit Quantum Electrodynamics Architecture for Gate-Defined Quantum Dots in Silicon
X. Mi, J. V. Cady, D. M. Zajac +3
We demonstrate a hybrid device architecture where the charge states in a double quantum dot (DQD) formed in a Si/SiGe heterostructure are read out using an on-chip superconducting…
